Warm when you stop. Breathable when you push. Fast-drying throughout. The Alpha Fleece Jacket runs Polartec® Alpha™ Direct through the body, sleeves, and collar - the fleece that actually performs rather than just looking like it does. A YKK Vislon® zip that runs smooth under gloves, thumbloops that keep your sleeves in place, flatlock seams that sit flat under a pack. No excess. No compromise. Regular fit. The workhorse mid-layer for the whole Manifest system.
